CUT-OUT.

Application filed June 26, 1922. Serial No. 570,887.

To all whom it may concern:

Be it known that I, ALBERT L. WYMAN, a citizen of the United States,residing at Paterson, in the county of Passaic and btate of New Jersey,have invented certain new and useful Improvements in Cut-Outs, of whichthe following is a specification.

The present e uipment for cutting off the current derived rom aconductor exterior of a building, as the wire from the aerial of awireless outfit, from a conductor within the building containing theinstrument to be operated is an ordinary knife-switch requiring theoperator to go outside of the building in order to operate it. Myinvention contemplates a cut-out which may be, operated with entirefacilit and reliability from the inside of the building and which willfurther comply with all the requirements of insurance underwriters andwill be extremely simple and compact in construction, inexpensive tomanufacture and capable of being installed without greater difficultthan attends the simple operations of drilling a hole through the wall,passing certain parts therethrough and securing the base of the cut-outin position by screws.

In the drawings,

Fig. l is a vertical sectional view of a building wall showing theimproved cut-out in position, said'cut-out appearing partly in sideelevation and artly broken awa Figs. 2 and 3 are horizontal sectionalviews on lines 2-2 and 3-3, Fig. 1;

Fig. lashows in side and end elevation a certain tubular insulatingmember; and

Fig. 5 shows in side elevation, partly broken away, and in transversesection, a modified form of said member.

Let a in F ig. 1 designate the wall of a building. A hole I) is boredtherethrough for the reception of a certain fixed part h to be referredto.

A mountin for certain parts is provided as follows: T ere is anelongated insulating block or base 0 which is attached to the exteriorof the wall a by screws (1 and which has projecting therefrom aboutmidway its length a forked post 6, which in the present instance is aseparate insulating part secured to the base by screws the slit or jawof the fork extending lengt wise of the base and preferably having ametallic wear-piece or lining f. In the base is tapped a hole 9 intowhich is screwed the threaded end of a tubular member h which fits thehole I) in thewall a. This member has parallel with its bore h alongitudinal passa which may either be a groove k therein %Fig. 4) or ahole it having its ends turned laterally (Fi 5). It protrudes at theinside of the wa a and on its inner end ma be secured by the screw 2'the escutcheon j. ixed to the base a by screws I: on opposite sides ofthe post 6 are metal clips 1 and m of the jaw type forming contacts orterminals; their jaws are arranged in the same plane as the jaw of thefork in the post e.

In the jaw of the post 6 on a screw n having a clamping nut 0 isfulcrumed between its ends a metal lever p the respective ends of whichare adapted to enter or clear the corresponding clips I and m when thelever is moved back and forth on its fulcrum.

This lever is adapted .to be operated by a thrustwise movable stem" orrod constructed as follows: The body 9 of the rod is preferably composedof insulating material, as

hard rubber, and it has embedded in one end i the threaded extensionpiece 1' onto which is screwed the fork s which receives in its jaw thelever p,,'a ivotal connection between them being affor ed by the screwt. The rod extends through-the bore h of the member 11. and it hassecured on its inner end the handle or knob u". The rod is adapted toslide lon itudinally through member h and its length for this purpose issufficient to allow the lever to move from en agement with the clip I toenga ement wit cli m.

A is the exterior con uctor leading rom the aerial or other energysource either to a suitable binding post '1)- on the end of lever padjoining clip Z or to the screw 'n, which may act as abinding post byhaving a bindin nut '11). B is the grounded conductor suitablyelectrically connected'with clip m. C is the service conductor whichextends from the clip I, with which it is suitably elec-.

trically connected, alon and in a groove :1: (Fig. 2) formed-in the%!1Ck of base a, then through the wall a, being there housed in thepassage of the tubular member h (to wit. groove h in Fig. 4 or hole Itin Fig. 5), and finally through a hole j in the. escutcheon j to andthrough the instrument D to be operated to ground; if desired, theconductor C may be in sections connected by the binding post 3 When themember It has the hole It therein the usual practice will be to embed.

are connected, so that A is grounded, and conuuctor C is cut out. I haveby the instrument described made it possible by a simple thrustmovement, entailing simplicity of construction and little alteration ofthe building wall,

to effect the connection or disconnection of a leading-in conductor (asA-- -C) without leaving the building and so as, at the same time, toprovide an ample gap, when the connection is disestablished, between thedisconnected parts of the. conductor. And by employing a lever fulcrumedbetween its ends I have made it possible to retain these advantages in acut-outwhich includes pro vision for connecting with or disconnectingfrom ground the conductor leading from the energy source, as,conductorA, when the instrument is put out of or in service.

-Having thus fully described my invention, what 1' claim as new anddesire to secure by Letters Patent is 1. In a means for electricallyconnecting and disconnecting from one side of a wall conductors one ofwhich is at the other side of the wall, the combination of a mountingadapted to be secured to the wall at said other side thereof and havinga projecting part adapted to extend into the wall, a lever fulcrumed inthe mounting and movable back and forth to establish and disestablishelectrical connection of the conductors, and means to move the lever onits fulcrum including a, sliding member adapted to penetrate the walland guided in and by said part.

2. In a means tor electrically connecting and disconnectin conductorsone 0 which is at the other side I of the wall, the combination of amounting from one side of a wall y,

me ias including a base adapted to be secured to the wall 'at said otherside thereof and a projectin g part detachably secured to said base andmeans to move the lever on its fulcrum including a sliding memberadapted to penetrate the wall, and guided by said part.

3. In ameans for electrically connecting and disconnecting conductorsone of which is at one side of a wall and the other of which extendsthrough said wall, the combination of a mounting adapted to be securedto the wall at said side thereof and having a projecting part adapted toextend intothe wall, said part having a passage for housing the portionof the second named conductor which extends through the wall, a leverfulcrumed in the mounting" and movabldback and forth to establish anddisestablish electrical connection of the conductors, and means to movethe lever on its fulcrum including a sliding member adapted topenetratev the wall and guided in and by said mounting.

4. In a means for electrically connecting and disconnecting conductorsone of which is at one side of a wall and the other of which extendsthrough said wall, the combination of a mounting including a baseadapted to be securedto the wall exteriorly thereof and a member havinga passage therein and detachably secured to the base and adapted toextend into said wall and to house in its passage the portion of thesecond-named conductor which extends through the wall, a lever fulcrumedin the mounting and movable back and forth to establish and disestablishelectrical connection ofthe conductors, and means to move the lever onits fulcrum including a sliding member adapted to penetrate the wall andguided in and by said mounting.

in testimony whereof I affix my signature.

ALBERT L. WYMAN.
